Bizhawk & Memory Addresses
Bizhawk is a multi-system emulator, and in our case it can be used to accurately read, freeze, and change memory addresses within the game. Use Tools -> RAM Watch to open the memory viewer, then Watches -> Add Watch to "Watch" a specific memory address. Right click a Watch and select "Poke" to change its value, or "Freeze" to freeze its value.
